Lipid levels in adults with cystic fibrosis.

Objective: To examine the hypothesis that an energy-dense, high-fat diet, which is necessary to maintain weight in adults with cystic fibrosis, does not result in high serum cholesterol levels.

Design: Dietary, anthropometric, and biochemical data were correlated.

Setting: A cystic fibrosis center in Pittsburgh, Pa.

Early infant diet and risk of IDDM in blacks and whites. A matched case-control study.

Objective: To investigate the role of early infant feeding in the development of insulin-dependent diabetes mellitus (IDDM) and to determine whether an association exists in both blacks and whites.

Research Design And Methods: Black and white diabetic subjects were recruited from the Allegheny County and Children's Hospital of Pittsburgh IDDM Registries. Extensive infant diet histories were obtained from the diabetic subjects and their nondiabetic siblings, who were used as nondiabetic control subjects.

Cholesterol screening in childhood: sixteen-year Beaver County Lipid Study experience.

To determine the extent to which cholesterol measured in childhood is predictive of values in adulthood, the investigators conducting the second follow-up of the Beaver County Lipid Study tracked the cholesterol values of 295 adults who had initially participated as children (ages 11 to 14 years) in a countywide school screening program. The follow-up study was conducted 16 years after the initial study, when the participants had reached a mean age of 28 years. The overall correlation (r) between baseline (1972-1973) total cholesterol values and the values found at the present follow-up was 0.

Zinc status of children with sickle cell disease: relationship to poor growth.

We examined the zinc status of 80 children with sickle cell disease (SCD) and 44 disease-free sibling controls aged 3 to 18 years. For both patients and controls, variations in serum zinc by age, type of hemoglobinopathy, and growth status were measured. The mean serum zinc concentration of patients was significantly lower than for controls (77.
